I have to remove the flywheel on my 200hp J200txecm to repair or replace the magnets. Not sure at the moment if any have to be replaced. They have shifted to where I can not feel a gap between them. The question is when I remove the flywheel what position, marking, timing will need to be done once it comes off and goes back on. I can get a used one for around $450 or pay mechanic $700 to do the work. Any help would be appreciated.
